I thought I had reached this limit at seven (the number I could fit on hooks along the side of my garage allotted for bikes). Then I left one at my brother's house in Pittsburgh, so I got number eight. Then I got two more, one on the work stand and one leaning against the others. So now I'm at 10.

If I can figure out a way to store bikes inside my wife's '68 Charger restoration project I can probably get to 20.
